DETAILED DESCRIPTION

[0034] In order for those skilled in the art to better understand the technical solutions of the present application, the present application will be further described in detail below with reference to the drawings.

[0035] Please refer to Figures 1-14 The embodiment of the present application provides a technical solution: a water source water quality monitoring device, which comprises a floating platform base 1, a top bin 12 is arranged on the top of the floating platform base 1, a plurality of solar panels 11 are arranged in a circular array on the top bin 12, a cylindrical dry cabin is formed in the floating platform base 1, a lifting unit 3 is arranged in the dry cabin, the lifting unit 3 comprises a lifting ring 31 which can slide along the central axis of the dry cabin, the lifting ring 31 is driven by a telescopic motor 30 arranged in the top bin 12 to realize sliding in the direction of the central axis, a plurality of water quality sensors 22 are arranged in a circular array on the lifting ring 31, the water quality sensors 22 are immersed in water for detection with the lifting ring 31 or are lifted out of the water to remain dry in the dry cabin, a protection mechanism 4 is arranged in the dry cabin, the protection mechanism 4 comprises a center support 41 arranged along the central axis, a plurality of elastic cotton pieces 411 are arranged in a circular array on the outer wall of the center support 41, and Figure 8As shown, the elastic cotton piece 411 includes a cylindrical elastic rod and a square cotton piece arranged on the elastic rod, and the elastic cotton piece 411 is arranged vertically along the central axis of the central pillar 41. When the water surface of the detected water source fluctuates strongly due to external force, the telescopic motor 30 drives the lifting ring 31 to lift, and the water quality sensor 22 is lifted out of the water. At this time, the square cotton piece is attached to the water quality sensor 22 for supporting, so as to protect the water quality sensor 22 when the water surface fluctuates strongly, and the telescopic motor 30 drives the lifting ring 31 to lift, and the square cotton piece absorbs the water on the surface of the water quality sensor 22 when the water surface does not fluctuate.

[0036] Further, the water quality sensor 22 can be an ammonia nitrogen sensor, a pH sensor, a conductivity sensor, and a turbidity sensor.

[0037] In still another embodiment of the present application, the top bin 12 is provided with a rotary motor 40, the output end of the rotary motor 40 is fixedly connected with the central pillar 41, and the rotary motor 40 is used to drive the central pillar 41 to rotate. The bottom of the dry cabin is provided with a foreign matter isolation cover 21, the foreign matter isolation cover 21 is used to isolate the impurities in the water, reduce the impurities attached to the water quality sensor 22, and when the lifting ring 31 lifts the water quality sensor 22, the rotary motor 40 can be started to drive the central pillar 41 to rotate, so that the square cotton piece contacts the plurality of water quality sensors 22 when rotating, and the water absorption efficiency of the square cotton piece is increased.

[0038] Further, as shown in the drawings, Figure 10 As shown, the central pillar 41 is provided with a one-way overturning groove 412 for rotating the elastic cotton piece 411, the one-way overturning groove 412 includes a blocking surface perpendicular to the central axis and a circular arc groove, and the elastic rod of the elastic cotton piece 411 is provided with a rotating protrusion, and the rotating protrusion is rotatably connected to the one-way overturning groove 412. The rotary motor 40 can be forward rotated and reverse rotated. When daily wiping and maintenance is performed, the rotary motor 40 is powered and reverse rotated, at this time, the elastic cotton piece 411 is overturned and inclined along the circular arc groove, so as to reduce the extrusion on the water quality sensor 22, and the wiping is performed in a light touch mode, and the purpose is to remove the residual water on the surface. When deep cleaning is required, the rotary motor 40 is powered and forward rotated, at this time, the elastic cotton piece 411 is blocked by the blocking surface, so that the elastic cotton piece 411 is bent when passing through the water quality sensor 22, at this time, the deep cleaning is performed, and the wiping force on the water quality sensor 22 is greater, and the cleaning ability is stronger.

[0039] In still another embodiment of the present application, a spiral groove 410 is formed on the outer wall of the center pillar 41, and a liquid circulating assembly 5 is arranged on the top of the center pillar 41. The liquid circulating assembly 5 includes a hose 52, and the two ends of the hose 52 are respectively a liquid outlet head 521 and a liquid inlet 522. The liquid outlet head 521 is directed to the top of the center pillar 41, and can deliver liquid to the top of the center pillar 41 and then into the spiral groove 410. The liquid inlet 522 is arranged at the bottom of the floating platform base 1, and can extract water at the monitoring site. A filter device can be arranged at the liquid inlet 522, and is used for filtering impurities. When the rotary motor 40 is powered and rotates in the forward direction, the hose 52 delivers liquid to the top of the center pillar 41. At this time, the liquid spreads on the elastic cotton sheet 411 along the spiral groove 410, and assists the center pillar 41 in deep cleaning.

[0040] Preferably, the center pillar 41 is provided with a toothed protrusion 51, and the top bin 12 is provided with a limiting cover 53 for covering the toothed protrusion 51. The hose 52 is arranged on the limiting cover 53, so that the hose 52 is located between the toothed protrusion 51 and the limiting cover 53. When the rotary motor 40 is powered and rotates in the forward direction, the toothed protrusion 51 rotates with the center pillar 41, and squeezes the hose 52. The hose 52 is squeezed onto the inner wall of the limiting cover 53, so that the hose 52 is continuously squeezed by the toothed protrusion 51 rotating in the forward direction, and water is pumped to the center pillar 41. The elastic cotton sheet 411 and the water quality sensor 22 are cleaned at the same time.

[0041] In still another embodiment of the present application, the center pillar 41 is provided with a limiting frame 42 floating on the liquid surface. The limiting frame 42 is provided with a waist round through slot 421 corresponding to the water quality sensor 22. The waist round through slot 421 is provided with a chamfer on the side facing the lifting ring 31. The telescopic motor 30 has two extension stations. In the first station, when deep cleaning is needed, the lifting ring 31 is moved by the telescopic motor 30, so that the water quality sensor 22 enters the waist round through slot 421 along the chamfer and is limited. At this time, the rotary motor 40 is driven to rotate in the forward direction, and the water quality sensor 22 is deep cleaned. In the second station, the lifting ring 31 is moved, and the water quality sensor 22 is extended into the water for detection.

[0042] Preferably, as shown in Figure 3 The lifting ring 31 is provided with a rotating shaft 311, and the turnover rod 32 is rotationally connected to the rotating shaft 311. The lifting ring 31 is provided with a limiting rod 312 corresponding to the rotating shaft 311, and the limiting rod 312 limits the turnover rod 32 from turning inward. When the water quality sensor 22 is driven to extend by the first station of the telescopic motor 30, the turnover rod 32 is limited from turning outward by the waist round through slot 421, and the limiting rod 312 limits the turnover rod 32 from turning inward. The axis of the water quality sensor 22 is parallel to the center axis, and the support capacity of the water quality sensor 22 is increased, which is more suitable for deep cleaning.

[0043] In another embodiment of the present application, a limiting frame 42 is arranged between the center pillar 41 and the impurity cover 21, and the limiting frame 42 floats on the liquid surface. When deep cleaning is performed, i.e., when the center pillar 41 is rotated in the forward direction, the limiting frame 42 is separated from the center pillar 41 and does not rotate together with the center pillar 41, thereby being limited by the limiting rod 312. In addition, the limiting frame 42 floats on the liquid surface, and when the water surface fluctuates, the limiting frame 42 can limit the waves and protect the water quality sensor 22 in the dry cabin.

[0044] Preferably, as shown in Figure 11 and Figure 12 The center pillar 41 is provided with a conical end 43, the conical end 43 is provided with a single coupling groove 431 with an inclined surface and a vertical surface, and the limiting frame 42 is provided with a coupling protrusion 420 matched with the single coupling groove 431. When the center pillar 41 is rotated in the forward direction, the coupling protrusion 420 is separated from the single coupling groove 431 along the inclined surface and does not rotate with the center pillar 41. When the center pillar 41 is rotated in the reverse direction, the coupling protrusion 420 is coupled with the vertical surface to drive the limiting frame 42 to rotate with the center pillar 41. The limiting frame 42 is provided with a plurality of push plates 422 arranged in a circumferential array. When the push plates 422 rotate, the liquid can flow through the impurity cover 21 to the outside for backwashing.

[0045] When the water quality needs to be detected, the telescopic motor 30 is started to extend to the second position, the water quality sensor 22 is inserted into the water to detect, and after detection, the telescopic motor 30 is retracted, the water quality sensor 22 is lifted into the dry cabin with the lifting ring 31, and then the rotating motor 40 is started to reverse. At this time, the elastic cotton sheet 411 is flipped and tilted along the circular arc groove to perform light wiping, and the residual water on the surface is removed. At the same time, the coupling protrusion 420 is coupled with the vertical surface to drive the limiting frame 42 to rotate with the center pillar 41. The limiting frame 42 is provided with a plurality of push plates 422 arranged in a circumferential array. When the push plates 422 rotate, the liquid can flow through the impurity cover 21 to the outside for backwashing. After a period of use, the telescopic motor 30 is started to extend to the first position, so that the water quality sensor 22 is limited in the waist circle groove 421 along the chamfer, and then the rotating motor 40 is started to rotate in the forward direction. The hose 52 supplies liquid to the top of the center pillar 41. At this time, the liquid diffuses to the elastic cotton sheet 411 along the spiral groove 410, and the elastic cotton sheet 411 is blocked by the blocking surface, so that the elastic cotton sheet 411 is bent when passing through the water quality sensor 22. At this time, deep cleaning is performed, the wiping force on the water quality sensor 22 is greater, and the cleaning ability is stronger. When the water surface of the detected water source fluctuates due to external force, the telescopic motor 30 drives the lifting ring 31 to lift and lift the water quality sensor 22 out of the water. At this time, the square cotton sheet is attached to the water quality sensor 22 for attachment and support. When the water surface fluctuates, the square cotton sheet serves as a buffer component to protect the water quality sensor 22.

[0046] The foregoing merely illustrates some exemplary embodiments of the application, and it will be appreciated that those skilled in the art will be able to devise various modifications without departing from the spirit and scope of the application. The appended drawings and description are illustrative only, and are not intended to be limiting.
